Dual-carriageway ends ahead
The W116 End of Dual Roadway road sign is a warning sign used to alert drivers that a dual roadway is ending ahead and that they are approaching a section where two-way traffic will operate on the same roadway.
The sign warns road users that the separation between the two directions of traffic is coming to an end. Drivers should therefore be prepared for a change from a divided roadway arrangement to a roadway carrying traffic in both directions.
W116 means End of Dual Roadway. It warns drivers that two one-way roadways are approaching a junction or transition where a roadway carrying two-way traffic is about to be entered.
W116 is a warning sign and does not by itself impose a speed limit or require drivers to stop. Drivers should continue to observe all applicable speed-limit signs, road markings, regulatory signs and other traffic-control instructions.
A dual roadway is a road arrangement where traffic travelling in opposite directions is separated into two one-way roadways, normally by a physical median or other form of separation.
At the end of the dual roadway, this separation comes to an end and traffic may continue on a roadway carrying vehicles travelling in both directions.
The change in traffic arrangement is important because drivers need to be prepared for oncoming traffic after leaving the divided section.
W116 signs may be used in advance of locations where a dual roadway ends and a two-way roadway is about to be entered.
Potential applications include:
The end of a divided roadway represents an important change in traffic conditions. Drivers who have been travelling on a one-way carriageway may soon encounter vehicles travelling towards them on the same roadway.
Advance warning gives drivers time to recognise the change in road arrangement and prepare for two-way traffic ahead.
This warning can be particularly important where the change occurs at higher speeds, near a median opening or where the transition is not immediately obvious.
The South African Road Traffic Signs Manual specifies that W116 and W117 End of Dual Roadway warning signs should be displayed together with the W212 Two-Way Traffic warning sign.
W212 provides the warning that two-way traffic is about to commence, while W116 or W117 warns of the end of the divided roadway arrangement.
W116 and W117 are both used for the End of Dual Roadway warning. The appropriate version depends on the alignment of the roadway and the way the road arrangement develops ahead.
The South African Road Traffic Signs Manual specifies that W116 should be used for particular alignment arrangements, including situations where the roadway being signed continues on the principal alignment of the approach roadway. The actual sign should be selected according to the road geometry.
Drivers approaching a W116 sign should be prepared for the transition from separated traffic to two-way traffic.
Drivers should:
The W116 sign should be positioned in advance of the point where the dual roadway ends so that drivers have adequate time to recognise the warning and prepare for the transition to two-way traffic.
The W116 and W117 signs should be used in accordance with the applicable advance-warning distances and adjusted where necessary to account for the geometry of the particular road layout.
The South African Road Traffic Signs Manual states that the W116 or W117 sign should be located in advance of the W212 Two-Way Traffic sign by a distance equal to V metres, where V is the operating speed in kilometres per hour. This distance may be adjusted where the road geometry requires special treatment.
Where the median island allows, the manual recommends displaying the End of Dual Roadway signs on both sides of the roadway.
The permanent W116 warning sign uses the standard South African warning-sign colour scheme:
A temporary version, TW116, uses a yellow retroreflective background with the same red retroreflective triangle and black semi-matt symbol.
Temporary W116 signs can be particularly useful during roadworks where traffic is temporarily diverted through a median opening and drivers are moved from a divided roadway arrangement to two-way operation.
W116 can have an important temporary application during road construction and maintenance projects.
For example, where one carriageway is temporarily closed and traffic is redirected through a median opening, drivers may need advance warning that the normal divided-road arrangement is changing.
The temporary TW116 sign may be appropriate for these situations, together with other temporary traffic-control and warning signs required for the work zone.
W116 and W117 should not be used simply to indicate that an undivided roadway becomes narrower.
The South African Road Traffic Signs Manual specifically states that these signs should not be used to indicate a road-narrows situation on an undivided roadway. A warning sign appropriate to the actual road condition should be selected instead.
The W116 End of Dual Roadway sign forms part of the South African road traffic warning-sign system. Where used on a public road, the sign should be selected, manufactured and installed according to the applicable South African road traffic sign standards and the requirements of the responsible road authority.
The Department of Transport publishes the South African Road Traffic Signs Manual as part of its road-infrastructure standards and guidance.
W116 signage may be relevant to organisations involved in road construction, maintenance, traffic management and infrastructure development, including:
W116 means End of Dual Roadway. It warns drivers that a divided roadway is ending and that a roadway carrying two-way traffic is about to be entered.
Yes. W116 is an advance warning sign that alerts drivers to the end of the dual roadway arrangement.
No. W116 is a warning sign and does not itself require drivers to stop. Drivers must follow any applicable regulatory signs, road markings and traffic-control instructions.
The South African Road Traffic Signs Manual specifies that W116 or W117 should be displayed together with W212 Two-Way Traffic to warn drivers about the change in traffic arrangement.
Both are End of Dual Roadway warning signs, but the appropriate version depends on the alignment and geometry of the roadway ahead.
Yes. TW116, the temporary version, can be particularly appropriate where roadworks create a temporary crossing through a median island and traffic changes from a divided arrangement to two-way operation.
No. W116 and W117 are specifically for the end of a dual roadway and should not be used simply to indicate that an undivided roadway becomes narrower.

Dual-carriageway ends ahead signs come in a variety of styles and formats, including danger signs, warning signs, and caution signs. Danger signs are used to indicate an immediate threat that could cause serious injury or death, such as high voltage areas or hazardous materials. Warning signs are used to indicate potential hazards that could cause injury, such as slippery floors or falling objects. Caution signs are used to indicate potential hazards that could cause minor injury, such as low ceilings or uneven surfaces. Another type of safety sign is the Dual-carriageway ends ahead sign, which is used to provide guidance on safe behavior. These signs can include instructions on how to use equipment or machinery safely, as well as reminders to wear personal protective equipment (PPE) or follow specific safety protocols. Dual-carriageway ends ahead signs can also be used to ensure compliance with safety regulations. For example, fire safety signs are required by law in most public buildings and workplaces. These signs indicate the location of fire exits, fire extinguishers, and other fire safety equipment.
